PRODUCT DESCRIPTION

Galvalume Steel Coil, also known as Aluzinc or GL, is a steel sheet coated with a mixture of aluminum (55%), zinc (43.4%), and silicon (1.6%). This unique coating provides exceptional corrosion resistance, heat resistance, and reflects heat effectively, making it superior to conventional galvanized steel in certain applications. The aluminum component offers excellent protection in atmospheric environments, while the zinc provides galvanic protection, making it ideal for a variety of industries.


Galvalume Steel Coil, also known as Aluzinc Steel Coil or GL Steel Coil, is a high-performance coated steel product. It features a unique alloy coating of 55% aluminum, 43.4% zinc, and 1.6% silicon, combining the advantages of both aluminum and zinc for exceptional durability.

The aluminum content provides long-term protection against oxidation and atmospheric corrosion, while the zinc offers galvanic protection to prevent rust formation. The silicon component ensures excellent adhesion between the coating and steel substrate.

Key Advantages

  • Outstanding corrosion resistance – 2–6 times better than conventional galvanized steel.

  • Superior heat resistance – ideal for high-temperature applications up to 315°C.

  • High reflectivity – reduces heat absorption in roofing and cladding.

  • Smooth, attractive surface – suitable for exposed architectural use.

Product Specifications

  • Thickness: 0.10–3.0mm

  • Width: 600–1500mm

  • Grade: JIS G3141 SPCC-1B, SPCC-1D

  • Applications: base metal for CRC, galvanized, and galvalume products; furniture pipes; greenhouse pipes; steel strapping.
